SEED-PLANTER.

Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed May 20, 1908. Serial No. 433,810.

To all whom it may concern:

Be it known that I, BENJAMAN FRANKLIN ROBINSON, a citizen of the UnitedStates, residing at Camp Hill, in the county of Talla poosa and State ofAlabama, have invented certain new and useful Improvements in of whichthe following is a specification.

My invention relates to certain new and useful improvements in cottonand other seed planters, and one object of my invention is to provide aconstruction in which the seeds will be fed at an equal rate, depositedat an equal depth and evenly covered.

Another object of my inventionis to provide a structure of thischaracter which will be simple and cheap in construction, composed offew parts, durable and not likely to get out of order.

With these and other objects in view my invention consists in certainconstructions, combinations and arrangements of parts, the preferredform of which will be first described in connection with theaccompanying drawing and then the invention particularly pointed out inthe appended claims.

Referring to the drawing wherein the same part is designated by the samereference numeral wherever it occurs, Figure 1 is a perspective view ofthe preferred form of my in? vention; Fig. 2 is a section taken on vline2-,2 of Fig. 3, and Fig. 3 is a section taken on line 3 3 of Fig. 2,looking in the direction of the arrow.

1, 1 designate a pair of bars connected at their front ends andextending outwardly from each other and rearwardly, the lower ends beingcurved downwardly and carrying the covering plows 2, 2. The rear ends ofthe arms are held in position by meansof the brace rod 3. At the forwardend the arms at their point of connection are provided with thedownwardly extending plow standard 4, carrying at its lower end theopening plow 5, the plow standard being shown as braced from the bars 1,1 by the braces 6, 6.

APivoted on the rod 7 extending between the bars 1, 1 are a pair of arms8, 8 which, for a distance rearward from the rod, extend parallel witheach other and between which is secured the seed hopper 9. Behind theseed hopper the bars extend toward each other, and in their lower endsis journaled a' wheel 10, the wheel being journaled in the arms 8 bymeans of the shaft or axle 11, to which the wheel is fast.

The hopper 9 is, preferably, and as shown, formed with parallel sidesand inclined ends,

and the bottom 12 thereof is provided with a top of the hopper to forman operating handle 17. i

Secured to the underside of the bottom 12 of the hopper and extendingdownwardlyV therefrom is a spout 18 by which the seed are directed intothe furrow opened by the plow 5 after they drop through the slot 13.

19 is a shaft journaled in the sides of the n er 9 and provided on oneend exteriorly hop of t e side of the hopper with a crank 20.

Mounted on the shaft 19 and in line with the slot 13 is a sector shapedseed agitator, formed of a hub 21 provided with radial iingers 22extending from the lower side of the hub and in close proximity to theupper edge of the slot 13.

23 is a U-shaped frame through the side arms of which extends the shaft19, the free ends of the U extending down adjacent to the bottom of thehopper and, preferably, being bent toward each other.

Both the hub 21 and the U-shaped agitator are preferably securedv to theshaft 19 by means of the set screw 24 passing, through Vboth theU-shaped frame and the'hub and nnpinging against the shaft 19. The shaft11 of the centrally dis osed Wheel. 10 is provided on one side of tl'lewheel with a crank 25 which is connected to the crank 20 of the shaft 19by means of the link 26. The crank 25is shorter than the crank 20, sothat the rotation of the wheel 11 as the frame is drawn over the groundproduces an oscillation of the shaft 19, which oscillates the sectorshaped agitator and the fingers of the U-shaped agitator, 'and causesthe seed to be fed evenly and steadily through the seed slot 13.

Preferably and as shown, the handles 27 are secured at their front endsto the frame 1 by means of the pivot rod '7 being held onto the rod bymeans of the nuts'28. 29,29 are a pair of braces which connect thehandles to the bars l near their rear, causing the handles to be rigidlyconnected to the frame carrying both the furrow opening and furrowclosing plows.

In the olperation of my seeder the seed hopper is -lled with eottonseed, and the v cranks 20, 25 and link 26 to oscillate the seetor shapedseed agitator carried on the shaft 19 and also the U-shaped agitator,consequently causing the seed to be evenly fed through the slot 13 andinto the furrow. As the frame carrying the wheel ll and the feed hopper9 is pivoted at the front end of the plow-carrying frame l the hopperwill be shaken by all the inequalities of the ground over which thewheel l() passes, thus assisting the even feed of the seed.

l realize that considerable variation is possible in the details ofconstruction and arrangement of parts without departing from the spiritof my invention, and l therefore do not intend to limit myself to thespecific forni shown and described.

That I claim as new and desire to secure by Letters Patent is:

l. in a seed planter the combination with a plow carrying frame, and awheel and seed hopper carrying frame, of an agitator ar ranged in theseed hopper and comprising ay shaft journaled in the sides thereof andha\ ing a U-shaped agitator mtulnted thereon and a hub mounted on theshaft and haring radial arms extending tlwrefrom, and means connectingthe supporting wheel and agitator shaft whereinv the former is operatedin the movement of the latter.

2. In a seed planter, the eonihimttiou with an outer plow carryingframe, an inner frame, a seed hopper mounted on said inner frame. awheel journaled therein, a seed agitator in the hopper comprising ashaft extending f across the same, a U-shaped frame mounted on saidshaft, a seetonshaped agitator mounted on the shaft and having radialarms extending downwardhv in line with the feed opening in the bot-tomof the hopper. and connections between the seed agitator and the wheelwhereby the former is operated in the revolution of the latter.

In testimony whereof l all'iX my signattue in presence of two witnesses.
